Seller neither refunding nor answering my emails. There is not a case number.

[doctor_jones_73]

Hi, I purchased a long time ago an item that, due to local customs stupidity, was returned to the seller (but after a long time, after the allowable period to open a case). The seller promised at that time (two month ago), to refund the amount, but it was never done and it is not answering my emails anymore.
I can´t open a case because it is old, and I do not fiinda any way to solve it with ebay.

Please help,

Thanks

Augusto
